getMinSharePreemptionTimeout

public long getMinSharePreemptionTimeout(String queueName)

Get a queue's min share preemption timeout configured in the allocation file, in milliseconds. Return -1 if not set.

getFairSharePreemptionTimeout

public long getFairSharePreemptionTimeout(String queueName)

Get a queue's fair share preemption timeout configured in the allocation file, in milliseconds. Return -1 if not set.

getFairSharePreemptionThreshold

public float getFairSharePreemptionThreshold(String queueName)

Get a queue's fair share preemption threshold in the allocation file. Return -1f if not set.
